Reliability is the biggest reason to carry a revolver.
Versatility is nothing to sneeze at, IMO.
There are a lot more M10s that can do that than there are shooters who can do that.
You really need to define “50 yard shot.” Hitting somewhere on a B27 is one thing, pulling off a head shot at that range is a wee bit harder.
Yeah, I shoulda been a bit more specific.
I contend a carry gun should be able to hit a one of those 5-6" coffee cans. That's about the size of a person's face, IMO. A head shot at 50 yards isn't difficult with a bit of practice & decent ammo.
I agree there's more guns than shooters who can do a 50.
